1. From the perspective of classroom teaching time, school education lasts 40 to 45 minutes, while each micro-class lasts only 7 to 8 minutes; Judging from the teacher's classroom teaching activities, in the past, the teacher faced a class of students, and only the teacher taught a piece of content in the environment of recording micro-lessons. From the actual teaching process of teachers, when facing students in a class, teachers can comprehensively use teaching, inspiration and questioning to promote teaching activities, while in micro-classes, all teaching links are completed by teachers alone, without real-time feedback from students and interaction between teachers and students; Wait a minute.
2. The class hours are short and the pace is fast, which requires teachers to be clear in the process of preparing lessons, and what they prepare should be what they can complete at normal speed within the specified time. According to the normal speaking speed, a person can speak about 120 words a minute, so the text of a speech prepared for 7 to 8 minutes should be controlled at about 840 to 960 words. Exceeding or insufficient will affect the rhythm of the lecture.
3. In micro-teaching, teachers should grasp two basic structures, namely knowledge structure and teaching structure. A teaching content is a complete knowledge structure, and a micro-course is also a complete teaching structure.
